Title: Improvements in dimming devices for head lights of motor vehicles
IPC: B60Q1/14
Filed: 1927-12-03
Abstract: 282,647. Bosch Akt.-Ges., R. Dec. 22, 1926, [Convention date]. Controlling consuming devices.-A step-bystep switch operated by a Bowden control gives full and dim lights in alternate operations. The switch may control a two filament lamp, two lamps, a lamp and fixed resistance or a lamp and variable resistance, the last giving gradual change of illumination. The device is particularly adapted for motor cycle headlamps and for handle-bar control. The switch, which is mounted on a fibre base 2 in a head-lamp casing 1, comprises a rotary metal-faced member with four teeth 8, the inclined faces of which engage in turn one of two contacts 10, 11 the other of which lies in a recess in the insulating material of the member and serves as a detent. One contact is connected to the main or only lamp or filament, and the other to the secondary lamp or filament, or to the resistance. The Bowden wire 16 turns an arm 4 with its ratchet disc 5, which is pressed against a ratchet disc 6 on the toothed member, through 45‹ at each operation. In a modification, a continuous resistance 19 in a fixed ring surrounding the toothed member is engaged by a contact 20 on the periphery of the latter and connected as shown in Fig. 9 with a lamp 29 so that in positions 22, 24, 26, 28 the lamp is dim and in the remainder bright. The contacts 10, 11 serve only as detents in this case.

Filed: 1925-12-28
Abstract: 257,153. Jahr, W. M. R. Dec. 28, 1925. Carbonizing fabrics. - In the drying and carbonizing of textile fabrics, the acidized fabric g is passed successively against a counter current of warm air through a preliminary drying section a, one or more drying sections b, b<1>, and a baking or carbonizing section c. In the section a the fabric is run horizontally to prevent draining and unequal distribution of the acid in the event of the machine being stopped. In the other chambers it is run vertically. In addition to a continuous current of air through the apparatus, the air is circulated in each section by fans v, v<1>: v<2> co-operating with heating boxes e and with suction boxes s each having exterior valves k for the admission of fresh air. In a modification, the fans v<1>, v<2> may be connected to the suction box of the section c and the fan v to the section b<1>. A heater m in section a prevents the formation of drops of moisture in the roof thereof.

Title: Improvements in the treatment of textile materials
Inventor: MANN RALPH JAMES
IPC: D06M15/423
Filed: 1956-11-01
Abstract: The lustre of textile materials is reduced by uniformly impregnating them with an aqueous solution containing (1) a non-ionic dispersing agent, (2) a catalyst selected from the group consisting of acids of dissociation constant at least 1 X 10-4 and salts thereof with volatile bases, and (3) a water-soluble condensation product of formaldehyde with melamine or urea, and then heating the impregnated material in an atmosphere such that the material remains wet. Suitable non-ionic dispersing agents are those produced by condensing 15-25 molecules of ethylene oxide with one molecule of (a) a fatty acid containing a chain of at least 10 carbon atoms starting from and including the carbon atom of the carboxyl group, (b) a fatty alcohol containing a chain of at least 10 carbon atoms starting from and including the carbon atom carrying the hydroxyl group or (c) an alkyl phenol in which the alkyl group contains a chain of at least 4 carbon atoms starting from and including the one directly attached to the benzene ring.  The catalyst is preferaby an acid which is substantially non-volatile in steam at 100 DEG C., e.g. citric, tartaric, lactic, oxalic or phosphoric acid, or a salt thereof with ammonia or methylamine.  The water-soluble melamine/formaldehyde condensation product used may be produced by reacting 1 molecular proportion of melamine with 1-6 molecular proportions of formaldehyde and may be applied to the material in a proportion corresponding to 4-12% of melamine, based on the weight of the material.  The impregnated material may be heated at 50 DEG -100 DEG C. in air saturated with water vapour or in saturated steam for 2-15 minutes and may subsequently be scoured in an aqueous solution of an anionic detergent, e.g. a long chain fatty alcohol sulphate or an alkyl aryl sulphonate.  Specified textile materials are acetone-soluble cellulose acetate, cellulose triacetate, cellulose propionate, cellulose acetate propionate, cellulose acetate butyrate, regenerated cellulose, synthetic linear polyamides, e.g. polyhexamethylene adipamide and polycaproamide, and synthetic linear polyesters, e.g. polyethylene terephthalate.  The Provisional Specification also refers to the use of solutions in which the non-ionic dispersing agent is replaced by an anionic dispersing agent.  Specifications 467,480, 469,688 and 568,438 are referred to.
